RedMax GZ7000 manual Fuel Handling, Gasoline requirements, Oil requirements

FUEL HANDLING

Fuel

Note! The machine is equipped with a two-stroke engine and must always be run using a mixture of gasoline and two-stroke oil. It is important to accurately measure the amount of oil to be mixed to ensure that the correct mixture is obtained. When mixing small amounts of fuel, even small inaccuracies can drastically affect the ratio of the mixture.

!	WARNING! Always ensure there is
	adequate ventilation when handling fuel.

Gasoline

•Use good quality unleaded gasoline.

•CAUTION! Engines equipped with catalytic converters must be run on unleaded fuel mixtures. Leaded gasoline will destroy the catalytic converter and it will no longer serve its purpose.

WARNING! Gasoline is very flammable. ! Avoid smoking or bringing any flame or sparks near fuel. Make sure to stop the

engine and allow it to cool before refueling the unit. Select outdoor bare ground for fueling and move at least 10 ft (3 m) away from the fueling point before starting the engine.

Gasoline requirements

•All 2-Stroke RedMax products are powered by Zenoah Professional-Commercial Duty, Hi- Performance, Hi-RPM, Air Cooled 2-Stroke engines. RedMax/Zenoah – Hi-Performance 2-stroke engines produce higher HP outputs as compared to standard Home Owner Duty or Light Commercial Duty production engines offered by most manufacturers.

•Exhaust emission are controlled by the fundamental engine parameters and components (eq. carburation, ignition timing and port timing) without addition of any major hardware or the introduction of an inert material during combustion.

•The RedMax/Zenoah engines are registered and certified with CARB (California Air Resources Board) and EPA (Environmental Protection Agency) to operate on CLEAN Mid-grade 89 octane or Premium, unleaded (lead-free) gasoline and RedMax air-cooled "MaxLife", synthetic blend Premium two-stroke engine oil mixed at 50:1 ratio.

•Unleaded gasoline is recommended to reduce the contamination of the air for the sake of your health and the environment.

•This Hi-Performance Air Cooled 2-stroke Engine requires the use of Minimum 89 Octane (R+M)/2 (Midgrade or Premium) clean gasoline. Gasoline may contain maximum of 10% Ethanol (grain alcohol) or up to 15% MTBE (Methyl tertiarybutylether). Gasoline containing Methanol (Wood Alcohol) is NOT approved.

IMPORTANT! If octane rating of the Mid Grade gasoline in your area is lower than 89 Octane use Premium Unleaded Gasoline. The majority of all 2-stroke engine manufacturers in the USA and Canada recommend using gasoline with 89 Octane or higher.

CAUTION! Gasoline with an octane rating lower than 89 will greatly increase the engines operating temperature. Low octane gasoline will cause detonation (knock) resulting in piston seizures and major internal engine components damage.

Poor quality gasolines or oils may damage sealing rings, fuel lines or fuel tank of the engine.

IMPORTANT! Failures caused by operating engines on gasoline with octane rating lower than 89 are not covered by the RedMax Two-Stroke engine warranty.

CAUTION! Alternative fuels, such as E-15 (15% ethanol), E-20 (20% ethanol), E-85 (85% ethanol) are NOT classified as gasoline and are NOT approved for use in RedMax 2-stroke gasoline engines. Use of alternative fuels will cause major engine performance and durability problems such as: improper clutch engagements, overheating, vapor lock, power loss, lubrication deficiency, deterioration of fuel lines, gaskets and internal carburetor components, etc... Alternative fuels cause high moisture absorption into the fuel/oil mixture leading to oil and fuel separation.

Oil requirements

•Use only RedMax "MaxLife", Synthetic blend Premium air-cooled two-stroke engine oil or oil certifiedto ISO-L-EGD (ISO/CD1378) standard AND one that is JASO-FD registered. RedMax air-cooled "MaxLife", Synthetic blend Premium two stroke engine oil and ISO-L-EGD (ISO/CD1378) AND JASO- FD oils arefully compatible with gasoline’s containing 10% Ethanol. RedMax air-cooled "MaxLife", Synthetic blend Premium two stroke engine oil and ISO-L-EGD (ISO/CD1378) AND JASO-FD oils are Universal and should be mixed at 50:1 ratio for all 2 stroke air cooled engines sold in the past regardless of mixing ratios specified in those manuals.
